What is the difference between a flared feeding and a compression feeding

The angle stop under your sink is one example of compression threads. Why is a flare connection preferred to a solder connection? Why is a flare connection sometimes preferred to a solder connection? A nut draws the flared tubing against a correspondingly shaped fitting, creating an extremely strong joint.

Bad flare, burrs on the pipe, wrong size flare, can all cause a flare fitting to leak. Can you over tighten compression fittings? Compression fittings work well if the pipe is clean and cut properly. Its often said in the trade to not over tighten a compression fitting, leaving you more thread in the case of a leak and not distorting the olive or fitting. Generally a nut will need one whole turn after hand tightening. How do you stop a compression fitting leak?

Tighten compression fittings firmly with two wrenches to crimp the ferrule onto the pipe Photo 3. Also make sure the pipe or tube goes straight into the fitting. Misalignment will cause a leak. If the fitting leaks after you turn on the water, try tightening the nut an additional one-quarter turn. Can I use compression fittings on soft copper? Learn more.

Let the other guy deal with leaks, and crimped tubes.

If you want a reliable, many time reconnectable, full flow, secure, leak resistant fitting, use a double flare fitting. The double flare is used on brake lines No compression fittings there Yes it can be a learning experience, doing your first few flare fittings Reading the 1 page sheet, that comes with most hand flare tools, is all that is needed.. If doing semi production I'm surprised a compression fitting holds up to hydraulic pressure.

We use air over oil intensifiers, and the reservoirs needs to be topped off fairly frequently. I am guessing the fixtures are slow leakers?

And in the past I have thought that it does not seem like we are getting the full clamping pressure in the hydraulics. What do you guys think - flared fittings be a big improvement?

They are ok for air pressure, and maybe up to PSI Hydraulic. Beyond that, i wouldnt trust them long term. Oldwrench , Jashley73 liked this post. Originally Posted by Marty Comstock.

They get moved just a bit, they go loose, and you can only tighten them so many times before you run out of tightening room.

And now I realize I'm an idiot because I have all the tools to make single and double flares Guess what I'm changing next chance I get.

I'm a bit taken back that you are making hydraulic fittings and don't have a few hundred dollars in flaring tools. Compression fittings are the perfect choice for high pressure applications. In combination with a high pressure tubing material like steel, large compression fittings can often be used at pressures in excess of 10, psig.

Can you use compression fittings on copper gas lines? Copper Fuel Gas Fittings. For copper natural gas systems joined with flared tube connections, flared brass fittings of a single 45 o flare type are used, Figure Compression fittings in a gas piping system are not permitted unless allowed by the authority having jurisdiction. Can I use a compression fitting with gas? Compression fittings can be used on gas pipes, although this should be left to a professional who is CORGI registered.

A pipe insert must also be used. Compression fittings are useful if you are working on a wet pipe as they will give a good seal where as a end feed or solder ring would not work.

What thread is a compression fitting? Compression fittings have straight threads and are made of brass or plastic and are often used on soft copper pipe and small-diameter tubing. The angle stop under your sink is one example of compression threads. Why is a flare connection preferred to a solder connection? Why is a flare connection sometimes preferred to a solder connection?
